To all whom t may concern.'

Be it known that I, EDWIN LYMAN MAYALL, a citi-zen of the United States, residing at Stockton, in the county of Sain Joaquinand State of California, have invented .new and useful Improvements in Vineyard-Flows, of

which the/following is a'speciiication This invention relates to plows, and pertains. especially I.to a plow or cultivator .adapted for' work in vineyards, hop fields,

and other places where the rows, or vines or trees are dlsposed at varylng distances apart.

Heretofore in cultivating vineyards sev- ,7 to'l2 feet apart. vIn plowing between these vinesjit is essential that the soil in successive plowing beturned alternately to- ,the vines, or their roots.

ablein one season, or at one time during the ward thefvinesand from the vines, and that care be exercised to avoid contact with Thus it is desirseas'on, to plow so that the soil is all thrown outwardly from the center toward two adjacent rows, and at a succeeding plowing that the soil be turnedin the opposite direction. This generally calls for theemploy-v The present invention provides a plow easily adaptable ment of two diierent plows.

to turnthe soil desired. 'f j In vineyard cultivation, is the need of plowing deepest in the center between the rows and to have the -furrows gradually grow shallower indepth toward the vines, so as not toiinjure the roots. The present invention arranges for an adjustment of the plows to plow at any desired depth, and also for an ingenious regulation of the suction of each plow.

Agaimit is not infrequent for the vines in a row tol be out of alinement, or for a vine to lean out of alinement, and it is therefore in whichever direction it is necessary inv plowing-to avoid injury to such vines asintrude into the space between the Y.

rows and at the same time it is equally important to plow up close to every vine. The present invention provides means whereby,

when the plow is close to the vines and the plows set to throw from the vines, the outer plows at each side of the gang areindependently adjustable at the will of the operator, toward and from the line ofdraft, so

.that any vine or obstruction may easily be dodged.

By the design of my special two-throw plow (2'. e., a plow having its plows set so that there are two sets working simultane- ,ously, either 'both throwing to the vcenter or both from the center) a great saving of power is accomplished through equalizing side draft. In ordinary gang plows wherev all' the plows turn the furrow in one direction, to right or left, there is a very heavy side draft in the direction of the land or away from the furrow. In my construction, this sidedrait is balanced andv results in a consequent savingof approximately 40%' in power required to pull a gang of given size. j

There are other objects and advantages accomplished by this invention which will appear hereinafter. The invention consists of the parts and the combination and construction of parts as hereinafter ,morev fully described and claimed, having reference to the accompanying` drawings, in whichj Figure l is a front view.

view. of the plow beam naled in an inverted-U-shaped standard 9,v

tangular shape, with the front ends of the frames connected across by a chord 2 and a drop truss member 2; the rear ends of the frames being inswept as shown at 3, to c on nect to therear caster wheel casting 4, in a manner more particularly to be described later. A v

Each of the plow'beam frames A ispreferably provided with an angular centralv member 5, suitably braced transversely at 6 and connected to the diagonal rear endportion '3; the forward end of the central partition member 5 spaced to. accommodate the front non-swivel supporting wheels 7 The machine is supported at its front on two of said non-swiveling wheelsZ, and at its rear end on .the swiveled caster wheel 8; vthe purpose of this method of support being indicated later. Each of the wheels 7 is jourf on which the frame is vertically slidable in the guide castings l0;-one of these castings v10 being bolted to the outside member of a beam frame A, .and the complementary casting bolted tothe forewardreach of the partition member. 5. The raising and lowering of the frame on the standards 9 may b e ac-. c'omplished by any` appropriate means. here shown, each side of the frameis independently adjustable through the medium of -the levers 11; each lever 11being fast to a respective rock shaft 12 journaled at the for- `ward end of the beam frames A-\A. Each rock shaft has a pair; of cranks 13 straddling a wheel 7 and connected bv links 111 to the lower ends of astandard9. Rocking lever 11 correspondingly rocks a shaft 12'causing the frame to move up and down on its guide 9; each lever being held in place by an lord'if nary ratchet and quadrant mechanism 15.

In order to facilitate the lifting of the heavy frame when it is desired to'raise the plow's, a spring 16 is providedv in connection with each lever, which has one end anchored to the frame andthe other end adjustabl'yv connected to the lever, as shown at 17 on one side of the lever fulcrum.

In order to adjust the levers 11 to have them convenient to the'fbperator, and to lie more or lessflat with reference to the frame,

' each rock shaft 12 is provided with-a cast projection 18, which is perforated at different 'points to receive a locking bolt 194; the desired angle ofthe lever being obtained by inserting the bolt 19 through one or the other ofthe perforations in the projection 18. 20 is a draft connection for attachment to suitabletraction means, as a traction engine, indicated at 22.

The rear ends of the draft connections 20 are adjustably connected to theV gusset plates 23, which -are rigid with the plow beanr r frames and extend therebeneath and are supportedand attached to, and are braced by the 'drop truss 2.

The rear diagonal inswe t ends 3 of the beam frames A embrace lbetween them a Vshortbeam member 25 which is secured at its forward end to the transverse brace 2G; the f rear ends ofi/these parts 3 and 25 being boltedthrough and secured to a seat on thecaster wheel casting 4, as shownin Fig. 10. The caste r\wh eel casting 4 is adapted to slide up and down on the4 standard 27er" caster wheel 8; there being front and rear` anti-friction bearings 28`-29 to `reducethc power required'to raise andlower the rear' end of the'frame o n said standard 27.

The following means are provided for raising-andlowering the rear end of the frame: Y 3() 1s anoperating lever arrangedin convenient reach of the operator-s s eat 31 and is loosely fulcrumedl on a rock shaft 33, which in turn is j'ournaled in and extends throughl the casting 4. Shaft 33 carries two spaced crank members 35-36 -connected by respective links,37-38,and a cross head 39,

which swivels on the .upper end with the caster wheel standard 27. Lever 30 is adapted Vto be adjustably locked' so as tocausethe shaft 33 toturn in unison with lever 30 by means of a cast projection 1,1 on

-the hub 42 of the crank member 36; the bolt 43 fitting perforationslll. in the projection 11. This adjustable connection of lever 30 with its rock shaft is similar to the connections 18- 19 of levers 11. Thus it will be seen that rocking lever shaft 33 is rocked to cause power to be transmitted through the cranks 35-36 to links 32-28 to raise and lower the vrear end of the frame; the

caster wheel 8 at all timesltrailin'g `idly at the. rear. Lever 3 0 is held at any desired point by the'usual ratchetand quadrant.

, The plows Bare arranged in two gangs, one gang for each beam frame A, and the two gangs so set that inthrowing their fur*- rows they willbalance one another. That is, plows in each gang are so set that both gangs will turn their furrows all toward the center, or all away from the centerf Furthermore, these plows are adapted4 to be interchangeable, not only one with the other in the same gang, but one gang withthe `other,. so that the same set of plows at one-f time will throw all their furrows outwardly toward the vines,or they will throw their furrows inwardly awayfrom the vines. In

addition to this, each plow is vertically adclamps 47. 'The brackets 46 are pivotallyv connected at one end, as at 48, to frame A; the other end of the brackets 46 having a vertical slot 49'to receive abolt 50 and allow for the tilting adjustment forward and back of bracket 46 to correspondingly raise or'V depress the toe or point of a plow, and so decrease or increase the plow suction.. By plow suction is meant the tendency of the plow to run more or less into the ground.

In order to set the plows for proper suction and prevent movement of the brackets.

46 after Atightening the bolt 50, there are provided set screws 51 threaded in a lug 52 on the bracket 46, so that the screws 51 may bear against the underside of the frame A and resist any` tendency of a bracket 46 to rock on its pivot 48.

A further advantage is that thisset screw providesa gage for the proper setting of the bracket 46 when the plows are transposed `from'one position on frame A to another position. Thus, when bracket 46 is transposed by placing the bracket with said sere against bottom of frame A, it -wll provide for the proper setting of plow bottom. Thus transposing plow bottoms .in this way need not change the suction or proper setting of the plow bottoms.

When plowing to throw the furrows toward the vines, or away from the center line of draft, the plows are set on`e behind the other in echelon, as shown in Fig. 1, the rear plows B being spaced only a couple of inches apart. In this case a 'colter wheel 55 is employed having a fixed standard 56, and

operating between the two rearmost plows, so that practically all 'the land is broken or pulverized by the conjoint action of the plows and colter. IVh'ere the rows are wider apart than the ordinary outwardthrow of'Y the plows, I may. increase the eXtreme outward throw of the plows by means of outriggers 60, Fig. 2, secured forward and to the outside of frames A; the brackets46 for these two forward outermost plows being secured `to the outriggers 60 in the same manner that the brackets are secured to the main portions of the frames A. rIhese out riggers 60 increase the width of the furrow cuts by approximately twenty inches; the

other plows being set one behind the other atv suitable points on their frames A.-

When' the machine is to be set to throw the furrows inwardly toward the line of draft andaway from the vines, the colter wheel 55 may be dispensed with. plows set to throw inwardly away from the vines they must as a rule, come much closer to the vines than where the furrow is thrown toward the vines. Consequently in order to give greater over-all spread to the plows and to enable the operator to dodge any 'vines which are outof line, or project into the area between the rows, there areJ provided lthe supplemental f adjustable lateral plow beams 61; there being one beam on each side of the machine pivoted near the forward end thereof, and each beam inde-A pendently adjustable toward and from the line of draft. Preferably these beams are m-ade of two strong bars of metal connected at their forward ends to ablock 62; block 62 being loose on a fulcrum pin- 63,which passes upwardly through an adjustable bracket 64. The upper surface of block 62 has a' conical. bearing 65 fitting a similar seat in the under-side of bracket 64. A

.brace member 66 springs from the beam 61 and connects to a. bearing block 67 having a similar underneath conical bearing68, fit- -ting in a similar socket in the bracket 6.4.

The purpose of the conical bearings 68 is to take up wear and avoid vibrations otherwise resulting from the severe strains placed upon the swinging beam 61.

t is manifest that-the fulcrum .for the plow beam-61 being so far from the plow 'the tendency to vibration is quite great and it is necessary to provide a rigid and stable .construction which will at-all times insure a good and perfect tit at the joints.

The bracket 64 is fulcrumed to its beam A at 70 on one side of pin 63, while the other end of the bracket on the opposite side of pin 63 ismade vertically adjustable so as to regulate the suction of the plows, carried by theswinging beam 6 This suction regulation is accomplished by means of a block 71 mounted by a wooden or easily friable pin 72 on frame A, and working in a vertical slot 73' on the bracket 64; the block 7-1 being vertically adjustable and secured by set screws 74. The outer end of the wooden pin 72 is supported in a usteel clip 75.. The purpose of this wooden pin 7-2 is to permit the plowB mounted on beam 61 to trip through the shearing of this pin v72, if at any time this bottom should snag a root of the vines. In othei` words, the pin A 72 will break yoff before the root breaks, so as to saye the latter from injury. The block 71 containing pin 72 is s o secured that when the pin is sheared or the plow bottom trips the set of the plow bottom is in nov With the way affected, or disarranged due to the fact of tripping and by restoring a new pin through block 7l restores the correct set ting of plow 4bottom B. v

y The lateral adjustment of plow bottom B attached to f each swinging` beam 6l toward and from the vines is accomplished 'by means of respective levers76. These levers are located in front of and convenient to the opera'tors seat 31. Each lever 1s fulcrumed at 77 and connects with a respective bell crank78, by means of a link 79; the opposite ends of the bell cranks being connected with their respective swinging beam 6l by means of a link 80. The position of the levers is maintained by the usual ratchet and quadrant.

Thus it is seen that each plow beam 61 l w-ith its plow is independently operable travelof the machine; each plow beam be-y from the operators seat toward and from the' vines without varying the direction of ing controlled by its respective lever 76.

Among the various practical features -of importance in connection with this machine is the fact of having its frontend mounted vron two non-swivel wheels, and'its rear end onia: swiveling or caster wheel 1n con]unc-.

tion with the comparatively short coupling 20to the traction engine, which' enable the machine to follow close in\the wake and path of the tractor, and thus make the necessaryA short turns required usually7 at the end of arrow, and between the'row .terminals and the ield boundary, known as the yhead lands. vThis s ort turn feature is quite important in th l v matter of a gang DOW?" Wlth this plow is comb-ined all the essentials of a practical, reversible gang lplow capable of throwing all its furrows outwardly, vor all its furrows inwardly; it is possessed of a great degree of ieXibility in widthof plow areaaccomplished in-a single The suction of the plows is c hanged by tilting the plow shank brackets 46 more or less; vor in the case ofthe outside swinging plows, adjusting the position of the block 7l. The vertical adjustment of the plows may also be controlled bythe levers 11-30. The line of the outer furrow. when throwing the furrow away from the vine, and the swinging beams4 6l are employed, is bent without `changing the travel of the machine, through the' mediumof one or the' other of the levers 76. The tripping of either of these outside plows on lbeams 61 is permittedby the use of the friable wooden pin 72."

` It is obvious that various changes in detailsl of construction Amay be made in this machine without altering its principle, vor

departing from thespirit of the invention.

It is manifest that all of these`operations of control of the machine and the plowwith theexception of changing the suction of the plow bottoms, are effected from the opera-4 tors seat. 1

vHaving thus described my inventionwhat I claim and vdesire to secure by Letters Patent is f f 1. ,Ina mold -boar'd gang plow,*the combination of a rigid frame, supporting wheels von which the main frame is adjustable verti` cally, a series of plows having right-hand mold boards mounted `at one side of the center of the frame and a series of plows l having left-hand mold plows mounted at the other side of the center'of the frame, theplows of one seriesbeing removable and interchangeable with the plows .of the other series said rigid frame com risino a air of spaced vllongitudinally extending beams at each side of the center thereof connected together to form a's'ubstantially rectangular shaped frame member, transverse members connecting lthe two pairs ofl beams together,
